Graph redlined but it DID record

I woke up to a normal graph, and then when I first went back in, it showed both a redline and yet all the data associated with my sleep. What happened here? I sent you a bug report. This is very weird. If the app actually didn’t record, it wouldn’t know how much deep sleep, etc. I tried to read the log file - it definitely was recording the data.

I use a Pebble Time running Rebble OS and dismissed from watch.
I have a Galaxy Note 8.
SaA beta version 20201007.

Thank you for looking into this matter.
